The field of the invention is patient monitoring systems. More particularly, the invention relates to an improved patient monitoring cable apparatus for in-line connection of multiple sensors.
An electrocardiogram (ECG) is used to monitor the heart activity of patients. To obtain information and monitor the electrical activity of the heart, a patient is connected to an ECG monitoring system with ECG cables. One type of ECG cable for monitoring is referred to as a 12-lead ECG. A 12-lead ECG requires the use of 10 electrodes for acquiring ECG signals. Generally, each of the ten electrodes require a separate connecting wire in the ECG cable. Further, multiple cables and connectors are often required when doctors must monitor more than just ECG signals. For example, when a doctor needs to monitor the blood pressure, pulse oximetry, and/or ECG of a patient, the doctor will usually use different cables and connectors for each monitoring instrument. The large number of cables and connectors can be bulky and difficult to organize. Therefore, there exists a need for an ECG cable with fewer wires to avoid the clutter and tangling of multiple wires and/or cables. Further, there exists a need for an ECG cable with improved signal quality and reduced artifact. In addition, there exists a need for an ECG cable that has improved convenience for simultaneously obtaining ECG signals as well as non-ECG signals, from blood pressure sensors, respiration sensors, pulse oximetry sensors, ECG sensors, etc.
One embodiment of the present invention provides a monitoring cable for use with a patient monitoring system. The monitoring cable includes a first end and a second end, an outer sheathing extending from the first end to the second end, a plurality of connecting wires, and a plurality of connectors. The plurality of connecting wires are each housed within the outer sheathing. The plurality of connectors are arranged along the monitoring cable to correspond with a desired location on the patient and are each coupled to at least one connecting wire.
Another embodiment of the present invention provides a monitoring cable for use with a patient monitoring system. The monitoring cable includes a plurality of connecting wires and a plurality of sensors. The plurality of connecting wires are housed within an outer covering and extend from a first end to a second end of the monitoring cable. The plurality of sensors are arranged in an in-line sequence from the first end to the second end of the monitoring cable and are coupled to at least one connecting wire. In addition, the plurality of sensors include a right leg electrode positioned as a first sensor in the in-line sequence and at least one non-ECG sensor.
Another embodiment of the present invention provides a patient monitoring system. The patient monitoring system includes a plurality of connecting wires, an interface, a plurality of connectors, and monitoring equipment coupled to the interface located at the first end of the monitoring cable. The plurality of connecting wires are housed within an outer sheathing of at least one monitoring cable. Further, the plurality of connecting wires each extend from a first end to a second end of the at least one monitoring cable. The interface is located at the first end of the at least one monitoring cable and includes a plurality of contact portions each connected to a respective one of the plurality of connecting wires. The plurality of connectors are each coupled to at least one of the plurality of connecting wires.
Another embodiment of the present invention provides a method of providing data. The method includes the steps of acquiring data using a plurality of sensors arranged in an in-line sequence from a first end to a second end of a monitoring cable, transmitting data acquired from the plurality of sensors to a plurality of connectors coupled with the plurality of sensors, and transmitting data from the plurality of connectors through a plurality of connecting wires each coupled with at least one of the plurality of connectors. The plurality of sensors include a right leg electrode positioned as a first sensor in the in-line sequence, a left hipbone electrode positioned as a second sensor in the in-line sequence, at least one midsection electrode positioned after the second sensor in the in-line sequence, a right side superior electrode positioned after the at least one midsection electrode in the in-line sequence, and a left side superior electrode positioned after the right side superior electrode in the in-line sequence. The plurality of connecting wires are housed within an outer cable and each extend from a first end to a second end of the outer cable.
Another embodiment of the present invention provides a system for monitoring a patient including a means for receiving ECG data through ECG data sensors from a patient and a means for transferring the ECG data from the ECG data sensors to monitoring equipment. Further, the ECG data sensors include a first sensor that is positionable on the patient to provide strain relief for the system.
Cable 20 may include multiple connectors 22, as indicated by connectors 22 a through 22 j. Each of the connectors 22 a through 22 j are coupled to at least one of the connecting wires 30. Cable 20 may also include a housing 23 between sensor 34 and connecting wires 30 to guide sensor 34 into a position for obtaining data. Referring to
As shown in
As shown in
Cable 20 may also include connectors 24, as shown by connectors 24 a through 24 c. Connectors 24 a through 24 c may be coupled to non-ECG sensors for obtaining non-ECG data. Thus, cable 20 may be used simultaneously for obtaining ECG data and non-ECG data. This eliminates the need for multiple cables or attachments during patient monitoring. For example, connector 24 a may be attached to a respiration sensor for obtaining respiration data on a patient. Connector 24 a may be positioned between connectors 22 i and 22 j, near a patient's throat or neck. Similarly, connector 24 b may be attached to a non-invasive blood pressure sensor for obtaining blood pressure data on a patient. Connector 24 b may be positioned after connector 22 j near a patient's arm. Further, connector 24 c may be attached to a pulse oxygen sensor for obtaining pulse oxygen data on a patient. Connector 24 c may be positioned after connector 22 j near a patient's finger, hand, ear lobe, or other suitable location.
According to alternative embodiments of the present invention, a multitude of connectors may be used to couple with any number or variety of sensors for obtaining other types of data on a patient. For example, cable 20 may be connected to a body position or activity sensor, a skin galvonic response sensor, a skin temperature sensor, etc. Further, connectors 22, 24 may be configured such that certain connectors can only be connected to certain types of sensors. For example, one connector 22 (e.g., an ECG connector) may only couple with an ECG sensor, whereas a second connector 24 (e.g., a non-ECG connector) may only couple with a non-ECG sensor. Alternatively, each connector 22 may be universally adaptable to both ECG connectors and non-ECG connectors. The possibility of numerous variations among connectors and sensors as well as the ability to attach a large number of non-ECG sensors to a patient with cable 20 helps eliminate cable clutter and thereby improve patient comfort and mobility. Furthermore, the reduced number of cables required improves care giver management by simplifying the overall connection process.
According to an exemplary embodiment of the present invention, cable 20 may include bumps or swells at the location of each connector 22 (e.g., for cables with internally integrated connectors) in order to assist a care giver in locating the proper connector and/or sensor position along cable 20. For example, as shown in
The design of the exemplary embodiment in
Cable 20 may also include a mating connector 46 located at first end 26 of cable 20. Mating connector 46 may include a number of contact portions each connected to a respective one of the connecting wires 30 to couple cable 20 to monitoring equipment, shown as but not limited to instrument 48. Further, cable 20 may be manufactured to fit different sized individuals. For example, according to a preferred embodiment, three different sized cables 20 are included in a patient monitoring system in order to fit small, medium and large individuals as necessary. In addition, cable 20 may be durable and flexible to accommodate different patient monitoring needs.
While the embodiments and application of the invention illustrated in the figures and described above are presently preferred, it should be understood that these embodiments are offered by way of example only. Accordingly, the present invention is not limited to a particular embodiment, but extends to various modifications that nevertheless fall within the scope of this application.
